I agree.
My only issue is free (infinitely cheap) power solves every problem. Maybe every problem ever (if you can spare a little time too).
Patents delayed 3d printers for decades. Lots of like examples of this stuff.
I’m pro-nuclear - the issue is always can governments be trusted for long term safety and storage of contaminants. Did the delayed focus prevent more catastrophes? Don’t know. Are governments more trust worthy now? Don’t know. Does Earth need nuclear to handle human population growth - sure, no other option.
If you throw in technology to store significant power for portability (e.g flying car batteries) - then you’ve hit the holy grail. As long as the weight isn’t too great.
My point was more around a good salesman can obscure the practicality of something in a present world, and sell turds as golden wings.
